If all you ever do to transport your laptop computer is to carry it from the house to the car and then from car to an office close by, you may be perfectly happy with a standard laptop bag. If, however, you do a lot of travelling where you spend a lot of time walking around airports or train stations you may find that the weight of your laptop bag on your shoulder is uncomfortable and even painful.

With this problem in mind  the bag manufacturers came up with the idea of a wheeled laptop case which puts the weight of the laptop on the wheels instead of on you. Wheeled cases are a great idea if you find carrying a laptop is a burden.
